Read the text on Cloud Computing and answer the questions that follow.

Cloud computing

means that instead of all thecomputer

hardware and software you're usingsitting on your desktop, or somewhere inside your company'snetwork, it's provided for youas a service

by another company and accessed over theInternet, usually in a completelyseamless way. Exactly where the hardware and software is located and how it all worksdoesn't matter toyou, the user—it's just somewhere up in the nebulous "cloud" that theInternet represents.

Cloud computing is a buzzword that means different things to different people. For some, it'sjust another way of describing IT (information technology) "outsourcing"; others use it tomean any computing service provided over the Internet or a similar network; and somedefine it as any bought-in computer service you use that sits outside your firewall.No matterhowwe define cloud computing, there's no doubt it makes

most sense when we stop talkingabout abstract definitions and look at some simple, real examples—so let's do just that.

Simple examples of cloud computing

Most of us use cloud computing all day long without realising it. When you sit at your PC andtypea query into Google, the computer on your desk isn't playing much part in finding theanswers you need: it's no more than a messenger. The words you type are swiftly shuttledover the Net to one of Google's hundreds of thousands ofPCs, which dig out your resultsand send them back to you. When you do a Google search, the real work in finding youranswers might be done by a computer sitting in California, Dublin, Tokyo, or Beijing; youdon't know—and most likely you don't care!

The same applies to Web-based email. Once upon a time, email was something you couldonly send and receive using a program running on your PC (sometimes called a mail client).But then Web-based services such as Hotmail came along and carried email off into thecloud. Now we're all used to the idea that emails can be stored and processed through aserver in some remote part of the world, easily accessible from a Web browser, wherever wehappen to be. Pushing emailoff into the cloud makes it supremely convenient for busypeople, constantly on the move.

Preparing documents over the Net is a newer example of cloud computing. Simply log on toa web-based service such asGoogle Documents

and you can create aword-processingdocument, spreadsheet, presentation, or whatever you like using Web-based software.Instead of typing your words into a program like Microsoft Word or OpenOffice, running onyour computer, you're using

similar software running on a PC at one of Google's world-widedata centres. Like an email drafted on Hotmail, the document you produce is storedremotely, on a Web server, so you can access it from any Internet-connected computer,anywhere in the world,any time you like. Using a Web-based service like this means you're"contracting out" or "outsourcing" some of your computing needs to a company such asGoogle: they pay the cost of developing the software and keeping it up-to-date and theyearn back the money to do this through advertising and other paid-for services.

What makes cloud computing different?

It's managed

Most_________________(important), the service you use is provided by someone elseand managed on your behalf. If you'reusing Google Documents, you don't have to worryabout buying licenses for word-processing software or keeping them up-to-date. Nor do youhave to worry about viruses that might affect your computer or about backing up the files youcreate. Google does allthat for you. One basic principle of cloud computing is that you nolonger need to worry how the service you're buying is provided: with Web-based services,you____________

(simple)

concentrate on whatever your job is and leave the problem ofproviding_________________(depend)

computing to someone else.

It's "on-demand"

Cloud services are available on-demand and often bought on a "pay-as-you go" or________________(subscribe)

basis. So you________________(typical)

buy cloudcomputing the same way you'd buy electricity, telephone services, or Internet access from autility company. Sometimes cloud computing is free or paid-for in

other ways.Hotmail issubsidised by_________________

(advertise), for example. Just like electricity, you canbuy as muchor as little of a cloud computing service as you need from one day to the next.That's great if your needs vary___________________(unpredictable): it means you don'thave to buy your own gigantic computer system and risk having

it sitting there doing nothing.

It's public or private

Now we all have PCs on our desks, we're used to having complete control over ourcomputer systems—and complete___________________(responsible)

for them as well.Cloud computing changes all that. It comes in two basic flavours, public and private, whichare the cloud equivalents of the Internet and Intranets. Web-based email and free serviceslike the ones Google provides are the most familiar examples of public clouds. The world'sbiggest online_________________(retail), Amazon, became the world's largest provider ofpublic cloud computing in early 2006. When it found it was using only a fraction of its huge,global, computing power, it started renting out its spare capacity over the Net through a newentity calledAmazon Web Services. Private cloud computing works in much the same waybut you access the resources you use through secure network____________________(connect), much like an Intranet. Companies such as Amazon also

Why is searching on Google seen as an example of cloud computing?

When you sit at your PC and type a query into Google, the computer on your desk isn'tplaying much part in finding the answers you need: it's no more than a messenger.

When you do a Google search, the real work in finding your answersis done by aGoogle computer.

How has cloud computing revolutionised email?

Now,emails can be stored and processed through a server in some remote part of theworld, easily accessible from a Web browser, wherever

we happen to be.

4.

What kind of documents can be prepared over Google Documents?

Word-processing documents, spreadsheets, presentations and others.

5.

Evaluation

The students appreciated the power of cloud computing and all agreed that it is the future. However,many of them were also critical about potential security concerns, which was pleasing to see. Thevideos helped them to understand the concept, and the vocabulary questions consolidated theirunderstanding of the text. Word formation proved to be challenging, with students regularly gettingsuffixes wrong.
